[Example]
<System configuration>
The overall configuration of the information processing system of this embodiment will be described with reference to FIG. The information processing system 1 roughly includes a server 10 used by the moving image producer 30 and a terminal 20 used by each of the plurality of evaluators 40. The server 10 and the terminal 20 are connected to each other via a network such as the Internet or a dedicated line, and transmit and receive information to and from each other.

The moving image producer 30 collects and analyzes the evaluations made by the evaluator 40 on the moving image using the server 10. The server 10 may further include a moving image production function that becomes a moving image creative and a moving image distribution function. The server 10 of this embodiment includes a control means 101, a display means 102, an input means 103, a communication means 104, and a storage means 105. The moving image producer 30 and the investigator requesting the evaluation from the evaluator 40 may be separate, and for example, a specialized researcher may be in charge of the evaluation. In that case, if a researcher who conducts Web research via the Internet is in charge of the evaluation, it is preferable that the list of monitors owned by the researcher can be used as a candidate for the evaluator 40.

The control means 101 is, for example, a processor such as a CPU that operates in response to a program on the memory or an instruction input by the moving image producer 30. The display means 102 is a display device such as a liquid crystal panel or an organic EL panel. The input means 103 is an input interface such as a mouse or a keyboard. The communication means 104 is an external communication interface such as a communication adapter. The storage means 105 is a storage device such as a ROM, RAM, or HDD. As the server 10, an information processing device such as a PC or a workstation provided with each of these means is suitable, and corresponds to the information processing device of the present invention. As the server 10, an information processing device that uses computational resources on the cloud may be used, and in that case, different information processing devices may be in charge of each function of the server 10. Further, the server for video distribution and the server for collecting and processing evaluation information may be separated.

The terminal 20 is an information processing terminal for the evaluator 40 to receive an evaluation request from the moving image producer 30, watch a moving image, input evaluation information, and send an answer. The terminal 20 of this embodiment includes a control means 201, a display means 202, an input means 203, and a communication means 204.

The control means 201 is a processor such as a CPU, and operates in response to a program or an evaluator's instruction input like the server 10. The display means 202 is a display device such as a liquid crystal panel or an organic EL panel. The input means 203 is an input interface such as a mouse or a keyboard. When the terminal 20 is a device including a touch panel such as a smartphone or a tablet, the touch panel may serve as both the display means 202 and the input means 203. In that case, the touch panel displays a moving image and accepts input by the evaluator 40 using a finger or a stylus. The communication means 204 transmits / receives information to / from the server 10 via the network. As the terminal 20, in addition to the above-mentioned smartphone and the like, any information processing terminal such as a PC or a workstation can be used. The program created by the moving image creator 30 operates in the native application installed in these information processing terminals and the Web application operating in the browser of the information processing terminal.

<Processing flow>
The processing flow of this embodiment will be described with reference to FIG. This flow starts from the time when the video creative used for the advertisement is produced. As an example, when multiple video creatives that are candidates for video advertisements used for advertising a certain product are produced, by applying this flow, it is possible to select the ones that are actually broadcast. According to this flow, it is possible to make selections based on the same evaluation criteria rather than sensuously.

The evaluator 40 can evaluate at any time while watching the moving image to the end. As the evaluation contents, positive information indicating that the evaluator 40 has a positive emotion and negative information indicating that the evaluator 40 has a negative emotion are assumed. That is, according to this embodiment, it is possible to acquire the favorability information for the moving image of the evaluator 40. At this time, information in which the time information indicating the timing (the number of seconds from the start of the moving image) and the result information indicating the evaluation contents by the evaluator 40 are associated with each other is generated as the evaluation information.

(Request evaluation from saving video)
After the flow starts, in step S101, the moving image creator 30 saves the produced moving image creative in the server 10.

In step S102, the moving image producer 30 inputs the necessary items for performing the evaluation by filling in each item of the predetermined format displayed on the display means 102 by using the input means 103 of the server 10. FIG. 3 shows an example of the format. Here, the format is a format using the Web browser 350 displayed on the display means 102, but any format may be used as long as it can be used by the moving image creator 30. In this example, the evaluation subject column 352, the evaluator column 354, and the moving image information column 356 are input.

The evaluation subject column 352 is the subject of the moving image to be evaluated, and includes the survey source (survey requester), the product / service name, and the like. The evaluator column 354 is a column for inputting what kind of evaluator 40 is to be targeted, and includes allocation information for designating the number of people by age group and gender, and objects of interest / interest. In addition, the number of evaluation stages may be input, and here, one stage is used for each of the "like" side and the "dislike" side, for a total of two stages. The moving image information column 356 is information about the moving image stored in the server 10, and includes the name of the moving image creative, the time information indicating the length of the moving image, the form information (for example, whether it is a vertically long moving image suitable for a smartphone, etc.). In addition, the evaluation by the evaluator 40 and the items required for the later report output are input. Further, the capture column 358 regarding still image acquisition will be described later.

In step S103, the evaluator 40 is selected based on the content input in the format and the evaluation is requested. If the researcher collects evaluation information as described above, select a suitable person from the list of monitors and request participation in the evaluation using direct mail or the push notification function of the application. .. In addition, a preliminary survey may be conducted to narrow down the evaluators more precisely.

(Acquisition of evaluation information)
In step S201, each evaluator 40 accesses the server 10 using the terminal 20 and watches the moving image displayed on the display means 202. Then, the evaluation is input using the input means 203 at an arbitrary timing during viewing. Here, with reference to FIG. 4, an example of a method in which the evaluator 40 makes an evaluation will be described. The terminal 20 in this example is a smartphone, and the touch panel also serves as the display means 202 and the input means 203. The touch panel (202, 203) includes a moving image display unit 220, a moving image progress status display unit 230, and an evaluation input unit 240. A moving image to be evaluated is displayed on the moving image display unit 220. Video progress display unit 230
Includes a time bar 231 and a progress display icon 232 indicating the current time when the width of the time bar 231 corresponds to the length of the moving image.

The evaluation input unit 240 includes a playback icon 241 and an evaluation navigation icon 242 (242a, 242b). While the evaluator 40 presses the playback icon 241 with the finger 401, the moving image of the moving image display unit 220 is played back. Then, the evaluator 40 slides the finger 401 placed on the reproduction icon 241 of the moving image along the evaluation navigation icon 242 according to the impression of the current scene. If you slide along the icon 242a on the left side, you have entered a negative rating that you dislike the current scene, and if you slide along the icon 242b on the right side, you have entered a positive rating that you like the current scene. You have entered it.
The evaluation input method is not limited to this example, and any format may be used as long as the timing and the evaluation content can be associated and saved.

Then, when the viewing of the moving image is completed, the process proceeds to step S202, and the evaluation information is transmitted from the communication means 204 of the terminal 20 to the communication means 104 of the server 10. The evaluation information includes time information indicating the timing of evaluation and result information which is the result of evaluation at that timing. FIG. 5 is an example of evaluation information. FIG. 5A is an example in which the time information and the result information are associated and saved. The control means 201 of the terminal 20 records in the table every time the evaluator 40 makes an evaluation using the touch panel (202, 203). Then, when the reproduction of the moving image is completed, the moving image ID and the evaluator ID stored in the format as shown in FIG. 5B are transmitted to the server 10 via the communication means 203. Information may be transmitted to the server 10 each time the evaluation is input.

Further, in addition to the favorability information indicated by the evaluation information, a questionnaire may be given to the evaluator 40 and the answer may be transmitted to the server 10. As the content of the questionnaire, for example, you may ask the impression of the entire advertisement, the scene that left an impression, the favorite element, and the like.

(Aggregation of evaluation information and display of evaluation information)
In step S104, the moving image producer 30 confirms that evaluation information has been collected from a predetermined number of evaluators 40 for each allocation condition, and performs aggregation and analysis. In step S105, the moving image producer 30 extracts the output still image for the report from the moving image. Then, in step S106, the report to the survey source is output in a predetermined format. These processes can be performed almost automatically by making the report corresponding to the input format.

<Characteristics of capture>
The capture still image acquisition for use in the report in step S105 will be described. In the format of FIG. 3, in the capture field 358, it is possible to input the time at which the capture starts / ends in the moving image, the predetermined interval of the capture time, and the like. Alternatively, the default settings may be applied to all videos. Based on this input content, the server 10 extracts from the time-series frame images constituting the moving image at intervals specified by the moving image producer 30, and stores the image in the storage means 105. By specifying the capture conditions in advance using the format in this way, the processing in the later report output can be automated.

FIG. 6 is an example of a sheet included in the report output in step S106, and FIG. 6A is a list of images for showing the contents of the moving image creative again. On the sheet 620 of FIG. 6A, the still image 622 captured in step S105 is arranged in time series together with the time display 624. The capture condition here is that a moving image having a length of 10 seconds is captured at intervals of 0.5 seconds from the first second to the end. By displaying the capture results in a list in this way, there is an effect that the scenes and elements of the video creative can be easily grasped.

<Output of evaluation information>
FIG. 6B shows an example of a sheet output based on the evaluation information. In the capture carousel 642 at the bottom of this figure, the captured and saved still images 622 are displayed side by side in chronological order. At the upper part, evaluation information obtained from a plurality of evaluators 40 for each scene in association with each still image 622 is shown as a graph 650. In the graph 650, the ratios of the positive evaluation 652, the neutral evaluation or the non-evaluation 654, and the negative evaluation 656 are displayed so as to be visible at a glance. Such a graph 650 can be created, for example, by classifying evaluation information obtained from a large number of evaluators 40 into classes at predetermined time intervals and calculating the ratio of evaluation contents at each time interval. Further, as the evaluation, only the ratio of the positive evaluation and the negative evaluation may be displayed.

According to such a sheet, the evaluation result information can be aggregated for each time of the moving image and displayed in chronological order. Therefore, since the moving image creator 30 can grasp the favorability information for each scene in the moving image at a glance, it can be useful for selecting and improving the moving image to be used for the advertisement.
Here, the favorability information is displayed as a percentage, but the number of positive evaluations and negative evaluations by the evaluator 40 may be displayed.

As described above, in the information processing method or the information processing apparatus information processing apparatus according to the present embodiment, the moving image producer 30 makes various settings related to the report in advance by using the format. As a result, the moving image producer 30 can automate the capture of the still image from the moving image and the output of the sheet in which the results are aggregated, so that it is possible to create a high-quality report at an early stage. Therefore, it will be effective in selecting and improving video advertisements.
